Warm, cloudy and very humid day with light NE winds. Great temps starting in the high 60s and ended up about 80 with the sun coming out in the last 10 miles. Rode with a great group including Rob, Wally, Tim, Shaun, Carrie, Jeff L, Angie, Tom S & Debi W (from Naperville), Jerry S (for the first 20 miles) and Zack (for the first 30 miles). Fast double pacelines made for quick travels on mostly good roads. Original plan to ride the 100 and then cut out the last 20-mile loop was scratched when it was determined that part of the 100-loop had gravel/chip seal. Instead, we rode one of the middle loops twice. Worked on rotating pacelines for part of the middle segment and was working well near the end. Only bad part was my collision/fall on the final 5 miles of Rich Road which resulted in a few cuts and bruises. Maybe my fastest ever 80 miler. Shaun, Jeff and Tim decided to add 18 miles to make it into a true century. Carrie, Rob, Wally and I had lunch and rehydrated at PJ's Courthouse Tavern in Sycamore.
